The list of prime factors of all numbers are

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 253 are 11 x 23

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 490, 280, 253, 432

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(490, 280) = 1960

GCD(490, 280) = ( 490 x 280 ) / 1960

= 490 / 280

= 490

Step2:

LCM(70, 253) = 17710

GCD(70, 253) = ( 70 x 253 ) / 17710

= 70 / 253

= 70

Step3:

LCM(1, 432) = 432

GCD(1, 432) = ( 1 x 432 ) / 432

= 1 / 432

= 1

So, Greatest Common Divisor of 490, 280, 253, 432 is 1
